Post-ictal changes in heart rhythm after brainstem SD

	n		Heart rate, beats/s		Heart rate variability (SDNN), ms		Skipped heart beats, total count
	Mice	Seizures	Pre-ictal	Post-ictal	Pre-ictal	Post-ictal	Pre-ictal	Post-ictal
Seizures with brainstem SD	6	9	8.12 ± 0.53	7.39 ± 0.34	22.8 ± 4.8	45.1 ± 7.0*	6.50 ± 4.13	65.5 ± 28.5**
Seizures without brainstem SD	6	9	8.37 ± 0.33	8.44 ± 0.49	20.2 ± 4.4	22.0 ± 3.6	6.61 ± 2.72	6.13 ± 2.80

*p = 0.016,

**p = 0.008 for pre-ictal versus post-ictal via Wilcoxon test.

SDNN, Standard deviation of all normal ECG R-R intervals.
